On the Oscar Wilde, pencils with edition numbers between 5,001 and 12,000 were also sold individually, as Montblanc intended; the first 5,000 belonged to the set. With other sets like Schiller or Kafka, individual pieces mostly arise because collectors take only parts (pen and ballpoint, or conversely pencil) and the set is broken up by the dealer. From a pure collector perspective, breaking up sets is unfortunate, since the consecutive edition numbers of the set ware should remain together; from a user's view it is, however, often the only way to get individual pencils.
